Description

A kind of immersed tube pipeline section floading condition manufacture method of box hat outsourcing
Technical field
The present invention relates to a kind of method of prefabricated immersed tube pipeline section in immersed tube tunnel, specifically refer to the immersed tube pipeline section of box hat outsourcing Floading condition manufacture method.
Background technology
The prefabrication of tube section method of immersed tube tunnel decides the success or failure of whole engineering, and at present, prefabrication of tube section all enters in dry-docking OK, dry-docking scheme has mobile dock scheme, fixing dry-docking scheme and batch production dry-docking scheme.
Mobile dock scheme is built or is rented large-scale partly diving exactly and refutes as packaged type dry-docking, completes on mobile dock Pipeline section prefabricated, then utilizes tugboat that half latent refuting is hauled to dive in the basin built up near tunnel, it is achieved pipeline section with refute The separation of ship, then section floating to tunnel location is completed sinking mating operation.
Fixing dry-docking scheme is the Large Foundation Pit made near tunnel, bottom surface absolute altitude the eating according to section floating of foundation ditch Water depth controls.Making pipeline section in fixing dry-docking, tube manufacture is opened dock gate after completing, pipeline section is hauled tunnel location and sinks Put.Fixing dry-docking is divided into again axis dry-docking, side to build a few class such as dry-docking, independent dry-docking.
Batch production dry-docking refers to carry out technology arrangement according to continuous-flow type prefabricated production line, and all pre-manufacturings are in Factory Building 24 Hour be carried out continuously, each sections after fixing pedestal upper, maintenance 3d, pushing tow forward, vacate and pour pedestal, next joint The sections neighbor that Duan Yugang ejects is prefabricated.So the most prefabricated pushing tow piecemeal, pours until completing whole sections, overall top It is pushed into shallow depressed place to carry out interim prestressed cable stretch-draw and form entirety, completes a fitting-out, be then shut off between shallow depressed place and pre-fabricated factory Sliding caisson, shallow depressed place pours water, and pipeline section floating moves to deep depressed place, finally opens deep depressed place transportation by driving on-the-spot to sinking.Denmark and Sweden etc. The workshop of immersed tube pipeline section is all had in country, and this pre-fabricated factory is suitable for Large-scale Super Long immersed tube tunnel (maybe can obtain length The region that phase stable pipeline section is ordered) prefabrication of tube section.The built port Zhuhai and Macao bridge of Oresund Bridge immersed tube tunnel and China It is exactly to use batch production dry-docking.
Existing dry-docking scheme is primarily present following defect:
(1) mobile dock is only applicable to 4 tracks and following situation, more than 4 tracks larger due to pipeline section, and matched half Diving, it is less to refute, and rents the half latent difficulty refuted bigger;
(2) mobile dock is in order to make refute latent with half of pipeline section separate the dive basin needing excavation deeper, to navigation channel and environmental effect Bigger;
(3) fixing dry-docking needs excavation Large Foundation Pit to carry out prefabricated tube section, and cost is higher and bigger on surrounding enviroment impact;
(4) batch production dry-docking floor space is relatively big, and cost is the highest, is only suitable for Large-scale Super Long immersed tube tunnel.
Therefore, it is necessary to prior art is improved.
Summary of the invention
In order to solve the problems referred to above, the invention provides the immersed tube pipeline section floading condition manufacture method of a kind of box hat outsourcing, the party Method floor space is less, it is to avoid excavate on the bank, reduces section floating waterway dredging amount simultaneously, and is applicable to various scale immersed tube tunnel Road.
The technical solution adopted in the present invention is:
The immersed tube pipeline section floading condition manufacture method of a kind of box hat outsourcing, it is characterised in that comprise the following steps:
(1) smooth location, construction steel plate job shop, outfitting quay and slideway district, described steel plate job shop includes cutting milling Workshop, limit, sandblasting Painting Shop and lamellar body assemble district;
(2) inner side welding ribbed stiffener and rivet after steel plate cleaved milling limit, sandblasting application and lamellar body assemble;
(3) described steel plate is positioned in slideway district welds U-shaped and weld temporary support;
(4) each 3~4 meters of scopes in two ends pour tunneling boring concrete, remainder pour base plate, whole mid-board and bottom 3~ 4m side wall concrete;
(5) steel end housing, steel end seal wall and guider are installed in two ends;
(6) pipeline section is slipped in water by jack and winch;
(7) delivery of described pipeline section is carried out remaining side wall to outfitting quay and concrete roof pours;
(8) remove described temporary support, and water tank component is arranged on inner tube segment by post-cast strip and interim manhole;
(9) pour post-cast strip concrete, carry out secondary fitting-out, afterwards by section floating to specifying position to carry out sinking.
The invention have the benefit that
(1) the prefabrication of tube section method of the present invention need not the latentest be refuted compared with mobile dock, can avoid the excavation of dive basin, therefore It can reduce the impact on environment, reduce construction costs, and the most not dived by half to refute is restricted the immersed tube tunnel being applicable to all scales Road.
(2) the prefabrication of tube section method of the present invention can avoid the excavation of Large Foundation Pit compared with fixing dry-docking, saves occupation of land face Long-pending, reduce training of channel amount during section floating, reduce construction costs.
(3) present invention can reduce floor space and port basin amount compared with batch production dry-docking, reduces construction costs, simultaneously The method is applicable to all scale immersed tube tunnels.
